Description

A kind of urheen

The utility model relates to a kind of stringed musical instrument, particularly a kind of national stringed musical instrument---urheen.

Urheen as a kind of musical instrument be widely used in China, with a long history, be subjected to liking of the people deeply, but also exist some weakness, as the qin bar because of the flexible distortion of the pulling force that bears string for a long time; The handle of tuning a stringed instrument directly inserts in the hole on the qin bar, and the friction force pinch grip of wearing or featuring stage armour hand and hole wall, string directly are wrapped in an end of handle, and is very inconvenient when adjusting the degree of tightness of string like this; A thousand pieces of gold mostly is one section tightrope and hitches qin bar chord face simultaneously, and a thousand pieces of gold easily produces displacement surface during performance influences tonal variations; Caused people that a kind of of urheen regretted and so on.

The purpose of this utility model be to provide a kind of qin bar can not produce flexural deformation, a thousand pieces of gold is easy to adjust and difficult become flexible, tune a stringed instrument convenient accurately, " urheen " that tone color is pure, tonequality is graceful.

The purpose of this utility model realizes as follows: vertical direction is inlaid with metal reinforced 14 in qin bar 1, increases the intensity of qin bar 1, increases the ability that qin bar 1 bears string 8 pulling force; By pressing string screw mandrel 6, pressed string block 5, nut 23 and a thousand pieces of gold 7 are formed top slidingtype a thousand pieces of gold system in the external pressure, a thousand pieces of gold 7 is that an xsect and longitudinal section all are similar to trapezoidal solid members, there are two parallel longitudinal grooves on its top, a thousand pieces of gold 7 is sandwiched between qin bar 1 and the string 8, rely on qin bar 1 with string 8 jack-up, a thousand pieces of gold 7 has a boss with qin bar 1 contacted one side, there is a vertical chute 16 at the position of placing a thousand pieces of gold on the qin bar 1, described boss is just placing the chute 16 on the qin bar 1, a thousand pieces of gold 7 can slide up and down along chute 16, reach the purpose of adjusting a thousand pieces of gold 7 upper-lower positions, be positioned at chute 16 tops on the qin bar 1 and be inlaid with a nut 23, the aperture of pressing string screw mandrel 6 to pass on the pressed string block 5 screws in the nut 23, and pressed string block 5 is pressed to qin bar 1 with string 8 is pressed in two longitudinal grooves on top of a thousand pieces of gold 7 string 8.Slide up and down a thousand pieces of gold 7, just can adjust a thousand pieces of gold 7, realize the function that tuning is transferred, and a thousand pieces of gold 7 can not move up and down or swing when playing to the string length between the qin sign indicating number 12; Adjust and press

string screw mandrel

6,5 of pressed string blocks can be tightened simultaneously or loosen string 8, realize the function that two string tones are finely tuned simultaneously.Top and qin bar at qin bar 1 vertically fasten sleeve 2, one end has little hook other end that screw thread is arranged and the screw mandrel 18 of tuning a stringed instrument of being longer than fixed muffle 2 can penetrate from the axial hole the fixed muffle 2, when having one of end of little hook and fixed muffle 2, the screw mandrel 18 of tuning a stringed instrument holds level with both hands when neat, the screw mandrel 18 threaded other ends of tuning a stringed instrument then are exposed at the outside of the fixed muffle other end, one end of fusiform handle 3 of tuning a stringed instrument is porose, the hole internal fixation has the nut 19 of tuning a stringed instrument, the handle 3 of tuning a stringed instrument entangles the screw mandrel 18 threaded ends of tuning a stringed instrument, nut 19 can with the threads engaged on the screw mandrel, the rotation handle 3 of tuning a stringed instrument, 18 energy of screw mandrel of tuning a stringed instrument are done axially advance and retreat motion in fixed muffle 2, on the little hook of screw mandrel 198 1 ends of tuning a stringed instrument, twine of string 8, the other end of string 8 is fixed on the bottom surface of qin holder 11, the rotation handle 3 of tuning a stringed instrument, the screw mandrel 18 of tuning a stringed instrument just can be tightened string 8 or be loosened, and becomes convenient thereby make to tune a stringed instrument, accurately, string 8 can not become flexible and in performance.The front portion of the base plate in the qin tube 10 is fixed with a sound column seat 21, is vertically fixing two sound columns 22 on the sound column seat; In order in qin tube 10, to produce resonance, volume is increased.The outside of the front and rear of qin tube 10 is inlaid with the preceding fastening hoop of metal material respectively, makes qin tube 10 can not produce the crack.

The utility model is owing to adopt bonding jumper to reinforce the qin bar, top slip or a thousand pieces of gold system in the external pressure have been adopted, adopted screw mandrel tune a stringed instrument and the qin tube in add sound column, the qin tube adds schemes such as hoop, make it have that the qin bar is not crooked, a thousand pieces of gold is difficult for becoming flexible, tune a stringed instrument conveniently, volume increases, qin tube characteristics such as crack not, thereby it is pure to reach tonequality, the tone color grace, and volume is grand, effect of changing voice not out of tune during performance makes this stringed musical instrument of urheen be elevated to the higher class of knowing clearly.
